windshield wipers

I have a 1985 honda accord lxi and the INT on my wiper control has stopped working so now I just have the slow and the fast. Any ideas? Thanks

If the washer motor works, then it could be the switch or the combined operation wiper/washer relay. Operation of the intermittant switch applies 12 volts to the green lead coming from the switch. So, if no 12 volts when the switch is selected to intermittant, then it is the switch. I have no idea where the relay is located but it probably under the dash.
